Agilent/Keysight CX1212A

The Agilent/Keysight CX1212A is a resistive sensor head that functions as a precision current measurement accessory for the CX1104A selectable shunt current sensor. It enables accurate dynamic current measurements up to 10 A with a flat frequency response extending to 20 MHz, making it well-suited for detailed current waveform analysis in electronic test environments.

Technical Specifications

• Maximum Dynamic Current Measurement: Up to 10 A


• Bandwidth: Up to 20 MHz (flat frequency response)


• Insertion Resistance: Typically 8 mΩ


• Included Accessories: 5 pairs of short wire pieces; compatible with banana adapter bundled with CX1104A for standard banana cable integration

Key Features The CX1212A incorporates a calibrated shunt resistor that delivers measurement accuracy across its operating range. The minimal insertion resistance of 8 mΩ ensures negligible impact on circuit performance during current monitoring. Connection methodology leverages standard banana cable compatibility through the supplied adapter, simplifying integration into existing test benches.

Typical Applications This sensor head works with precision current monitoring in electronic test and measurement environments where dynamic waveform capture and accurate current characterization are required. The 20 MHz bandwidth supports analysis of transient current behavior and high-frequency switching events.

Compatibility & Integration The CX1212A is purpose-designed to operate with the Keysight CX1104A selectable shunt current sensor. It connects devices under test (DUTs) to measurement instruments via standard banana cable connections. Integration with the CX3300 Series Device Current Waveform Analyzer extends analytical capabilities for comprehensive current waveform characterization.
